Evaluation of effectiveness of municipalities in black sea region with data envelopment analysis

This study aims to measure to what extent 18 municipalities in the Black Sea Region are effective compared to each other. The Data Envelopment Analysis (DEA) method was employed to measure the effectiveness of municipalities in comparison to each other. To calculate effectiveness values, the input-oriented CCR and BCC models from DEA models, as well as the input-oriented dual CCR models for ineffective municipalities were established based on the CCR model results. In the present study, input variables were determined as goods and services procurement expenses, personnel expenses, and capital expenses, while output variables were determined as enterprise and property revenues, tax revenues, and other revenues. The LINDO 6.1 software program was used in the solution of the models. According to the solutions of CCR and BCC models, the municipalities of Bartın, Bayburt, Bolu, Çorum, Düzce, Karabük, Kastamonu, Ordu, Rize, Samsun, Sinop, Tokat, and Trabzon are fully effective, while Amasya, Artvin, Giresun, Gümüshane, and Zonguldak are not. According to the solutions of dual CCR models, the municipalities of Bartın, Bolu, Çorum, Düzce, Karabük, Ordu, Samsun, Sinop, Tokat, and Trabzon are fully effective, while Amasya, Artvin, Bayburt, Giresun, Gümüşhane, Kastamonu, Rize, and Zonguldak are not. Moreover, the dual CCR model results suggested new input values for the ineffective municipalities to achieve effectiveness.
